Backup failure w/ LyX 1.5.2

[Dave Hewitt]

Whenever I try to save LyX documents (File -> Save or Ctrl-S), I get a 
Backup Failure notification (image attached). After I hit OK, the Save 
option in the File menu is grayed out, indicating that the file has been 
saved. When I reopen the file, it looks fine, so the file itself is saving 
OK. Apparently LyX is (was, below) only having a problem accessing the 
backup directory.

In Tools -> Preferences -> Paths, my backup directory is given as 
C:\Program Files\LyX 1.5.2\backup, but no directory called 'backup' was 
created with the installation. I created a new folder in that location and 
named it 'backup', and (not surprisingly) everything now works fine.

I'm just curious as to whether this is the most appropriate solution? If 
so, why was there no 'backup' directory created in the first place when LyX 
defaults to that path for backups? And, no files of any type are appearing 
in this new backup directory I created, so where are these backups going 
(i.e., what is the purpose of this folder)? Finally, are any of the other 
paths in the Preferences likely to be affected in this way?
